Steps 1- 9, refer to FIG. 7.

1.Install the lines from the master divider valve to the secondary divider valve, but do not completely tighten the connection at the secondary divider valve’s inlet.

2.Remove the performance indicator port plug or the performance indicator from the working valve sec- tion on the master divider valve assembly corre- sponding to the outlet port and the line connected to the secondary valve.

3.Attach a hand pump filled with clean, filtered lubri- cant on the master divider valve that was opened in Step 2.

4.Operate the hand pump until air-free lubricant is observed flowing freely from the secondary valve’s lube inlet connector.

5.Tighten the fitting at the secondary valve’s inlet while lubricant is still flowing.

6.Remove all of the indicators or indicator port plugs from the secondary divider valve’s working sections.

7.Operate the hand pump again until air-free lubricant is observed flowing out of all the secondary divider valve’s indicator ports.

8.Reinstall all of the performance indicators or port plugs in the secondary divider valve while lubricant is still flowing from the ports.

9.Remove the hand pump and reinstall the perfor- mance indicator or indicator plug removed in Step 2 into the master divider working valve’s open port.
